Raw khoom specifications raugalvanized ntawv
1. Raw khoom specifications rau cov neeg sawv cev tiv tauj. Zinc chloride thiab ammonium chloride tiv tauj cov neeg ua haujlwm yuav tsum tsis muaj xim lossis lub teeb daj. Yuav tsum muaj ob qib xaiv los ntawm, thiab lawv yuav tsum muaj cov neeg ua dej ntub dej.
2. Khoom specifications rau zinc-aluminium alloy profiles. Cov muaj pes tsawg leeg ntawm zinc seem hlau ntxiv rau zinc pas dej thaum lub sij hawm kub-dip galvanizing txheej txheem yuav tsum yog: aluminium=4.5-5.0%, tooj liab=mus txog 0.001%, magnesium=0.002%, lead=0.003%, hlau=0.003%, cadmium=0.002%, Sh=0.002%. Nco ntsoov tias tag nrho qhov hnyav ntawm ib daim ntawm zinc seem yog li 9.5-10kg, thiab nws yog qhov zoo tshaj kom muaj daim ntawv pov thawj ntawm kev ua raws li tus qauv no thaum muab nws.
3. Cov txheej txheem raw khoom rau zinc-aluminium profiles: kub-dip galvanized zinc ingots (txias dov steel phaj) yuav tsum ua raws li cov cai ntawm ASTMB{{0}}. Thawj tus qauv txhuas tshaj tawm hauv thaj av sab hnub poob yog li 1%. Qhov sib xyaw ua lag luam ntawm zinc ingots yuav tsum yog: txhuas yuav tsum yog 0.5-1.4%, hlau<0.05%, cadmium <0.01%, copper <0.002%, tin <0.001%, aluminum <0.005%. Note that the total weight of a zinc ingot is approximately 25kg, and when supplied, there should be a certificate of conformity to this specification as far as possible.
